BOOK-HOLDER.

Specification of Letters Patent.

Patented July 26', 1921.

Application filed April 13, 1921. Serial No. 461,133.

T 0 all whom it may concern:

Be it known that I, ERNs'r BRAUCHLI, a citizen of the SwissConfederation, residing at St. Gallen, Switzerland, have inventedcertain new and useful Improvements in Book-Holders, of which thefollowing is a specification.

The present invention has reference to certain new and usefulimprovements in book holders, and it relates more part1cu larly to aconstruction of book holder which can readily be adjusted to differentangular position relative to the readers face, so that it will hold thebook substantially parallel to the readers face with the reader insitting-up or more or less recumbent position.

In order to make my invention more readily understood, I will nowdescribe it in detail in connection with the accompanying drawing, inwhich Figure 1 is a front view, of the holder; Fig. 2 is a fragmentalsection on line A-A, and Fig. 3 a section on line BB of Fig. 1; Fig. 4L-is a top view of the device, partly in section, and Fig. 5 shows thebook holder in connection with a floor stand supporting also a tray forsmoking utensils or the like and a reading lamp.

The main carrier bar presents lateral guide arms 4. of U-shapedcross-section and intermediate thereof a cylindrical enlargement 5; aclamp 1- surrounds this middle portion 5, the laterally extending clamparms 15 being alinedly perforated to receive the tightening bolt 3 withwing nut 17. The bolt 3 is fixed on the socket member 2. The doubleframe 6, of upstanding front and rear loops, the two rear ones of whichare connected by a slightly curved bridge piece 7, is rigidly supportedon the carrier bar.

Two flat arms 8, terminating outwardly in eyes 16, are slidably arrangedwithln the carrier bar and are provided with stops 9 (Fig. l) to limittheir relative displacement tothe extent of the length of theenlargement 5. In the eyes 16 engage the lower ends of the bent-off leafholders 10. The holder P (Fig. 5) is secured by the socket 2 to one endof an elbow support 11, whose other ends is suitably secured to a floorstand 12, which also carries a small table l3and a reading lamp 14.

For inserting a book, first the arms 8 are drawn out of their guidingarms 4:, the opened-up book is then inserted with the cover boards inbetween the respective pairs of front and rear loops of the frame 6, andlastly the leaf holders 10 are swung into position in contact with theunprinted outer margins of the book pages, the arms 8 beingsimultaneously shoved home in their guide arms to the required extentdepending upon the width of the pages. The wing nut 17 is now eased, theentire holder P with the clamped book is tilted into the desired angularposition and the clamp 1 is then tightened again on the cylindricalportion 5 of the carrier bar by manipulation of the wing nut 17.

By dispensing with the floor sand, provision may be made to clamp thesupport 11 or the clamping member 1 directly onto a chair, bedframe, orother piece of furniture.

What I claim is 1. In a device of the character stated, a carrier bar,presenting a cylindrical middle portion and laterally extending guidearms of U-shaped cross-section, a double frame upstandingly fixed tosaid carrier bar and comprising two pairs of front and rear loops, abridge piece connecting the two rear loops, arms slidingly arranged insaid guide arms, eyes forming the outer extremities of said slide arms,stop means associated with said slide arms, leaf holders swinginglysupported in said slide arm eyes, and clamping means for releasably.securing said as semblage of parts to a fixed object.

2. In a device of the character set forth, a carrier bar presenting acylindrical middle portion and laterally extending guide arms, a doubleframe upstandingly fixed to said carrier bar and comprising two pairs offront and rear loops, adapted to receive between them the opened-upcover boards of a book, a bridge piece connecting the two rear loops,arms slidingly arranged in said guide arms and eyes at the extremitiesof said slide arms, stop means on said slide arms designed forcooperation with said cylindrical carrier bar portion to limit therelative longltudinal displacement of said slide arms, bent-off leafholders supported in said slide arm eyes, and clamping means,

comprising a slit tubular member snugly screw bolt and nut meanscooperating with surrounding said cylindrical carrier bar said aperturedarms and said screw bolt in portion, two apertured arms respectivelyfixed connection with said adjustably securlatera-lly extending from theslit edges of able member. 10 5 said tubular member, a member adapted toIn testimony whereof I affix my si nature.

be adjustably secured to afixed object, and ERNST BRAU HLI.
